EdenOne,
The first thought that came to mind is that the Israelites were hill-dwelling Canaanites (poor cousins of the Canaanites who lived on the richer soils of the plains).
This is an area that I am toying with in my mind -- the original Israelites (clearly they had taken onboard the Canaanites' supreme God El, as is shown by the name they gave themselves: "Isra-EL"..
At the moment, I have not investigated that passage and thanks for pointing me to it.
I take a degree of caution with "historical" statements in the Bible, and I will need to take into consideration who wrote it, when, and for what local purpose.
A fundamental concept was that each city, each society, and so forth had its own god. Therefore when a city was defeated, it meant that their god was weaker.
Yes all those societies had plural gods and goddesses. Judah was dominantly polytheistic up to the Exile. The minority "Yahweh-alone" sect was largely drawn from a group in the Temple. When it was destroyed by Babylon, these Yahwists lost the symbol of their power.
They convinced most that the parlous state of Judah resulted from Yahweh's displeasure that they had not followed the "Yahweh-alone" party. They returned with promotional writings (later OT Scripture), Yahweh alone, and a determination that their temple be built.
No wonder the people who had been left on the land were not happy to see them come back from Babylon.
